Under fluorescent lamp illumination of 500 lx, 429 Munsell color chips were used in a categorical color naming using 11 basic color terms to test how colors appeared to change when young subjects wore filters that allowed 20-year-olds to see the outside world as 80-year-olds do. The results revealed no significant difference in categorical color naming in terms of apparent-color or surface-color perception. This suggests that old people can recognize blue colors for example despite the ocular-spectral-transmittance change of their aging lenses, and that the color constancy mechanism plays a critical role in color appearance compensation for older people.
